Enlightenment is a small, fast, customizable "window manager" that works quite well with Puppy. Enlightenment boasts menu transparency, multiple and virtual desktops with easy switching, an icon bar, a desktop pager, epplets (like very small widgets), and a few special effects like "ripples" on your desktop. It takes some getting used to since it is a little different than the other window managers, but give it time and use your tooltips by hovering the cursor over desktop items.
